Bettering the Bifocal: Multifocal Lenses

If you're middled-aged and having some trouble reading books and newspapers, you might have developed presbyopia, a common age-related condition that prevents you from clearly seeing close objects. But, this doesn't mean that individuals who already have glasses to tend to their problems with nearsightedness are required to carry around two pairs of glasses. Multifocal lenses, which rectify both near and distant objects, help you see well at all distances with one pair of glasses.

Multifocals are a vast improvement on bifocals. Bifocals corrected problems with both near and far vision, but left everything in between a little blurred. In an effort to correct this issue, progressive lenses were made, which give you a transition part of the lens which lets your eyes to focus on distances that are somewhere in the middle. But what creates this effect? Progressive lenses are expertly curved, unlike a bifocal lens, which is sharply divided. Because of this, progressive lenses are also called no-line lenses. This makes for not just better vision at all distances, but also nice, easy transitions in between.

These lenses, although better, may require some time to get used to. Even though the invisible transition of progressive lenses results in a product that is aesthetically pleasing, the lens's areas of focus are relatively small, so that there's also room for transitional areas.

Even though multifocal lenses (also called trifocals) are for presbyopia, bifocals are often used to help young patients with eye problems such as eye teaming, or being unable to focus properly, which causes eye strain.

When the time comes to get fitted for multifocal lenses, make sure it's with an eye care professional you trust. Multifocal lenses work best when they're customized to your unique eyes, needs and line of vision.

Glasses that aren't properly customized to you can lead to headaches, eye strain or even nausea. Unfortunately, presbyopia is a reality of aging. But don't forget; multifocal lenses can make all the difference.
